not removable in 3
cleaning attempts,
it is defined as
fixed particulate.
Fixed

allowed in this area.

After the connector has been verified to be cleaned, it should be immediately inserted into
3
the adapter buildout of the optical component. This will assure maximum cleanliness and
effectiveness of the connector.
........................................................................................................................................................................................................................
If the cleaned connector cannot be immediately connected to a corresponding adapter, the
4
connector ferrule must be protected with a connector dust cap. Before placing the cap on
the ferrule, make sure the cap is clean. This can be accomplished by inserting a CLETOP
stick cleaner (swab) of the same inside diameter as the cap (either 2.5 or 1.25 mm) and
rotate the stick 360 degrees three (3) times. Following this procedure, carefully place the
cap over the ferrule. When the cleaned connector is ready for assembly, it should be re-
inspected for cleanliness prior to connection.
